I think this post will be useful to someone new to the iOS development. One of the most important and commonly used classes in Cocoa is UIViewController. Creating any non-trivial application will involve subclass and creating your own view controller. There are a lot of topics and tutorials elsewhere, so I’m not going to repeat […]

I have done a bit of iOS development lately. While trying to get myself familiarized with the new platform, I came across this book titled “Programming iOS 4″. I skimmed through some sections and found this paragraph: You should not use a view controller in any other way. It is not, for example, appropriate to […]

I recently ran into some hard to find memory leaks. The program only runs on Linux. The memory leaks are detected using a custom memory allocator (using an atomic counter for allocation/deallocation size). In single thread mode, the program terminated without leaking, but running in multithread mode resulted in 1.7 to 4 KB of leaked […]

I haven’t really done much web development in the last 8+ years or so, and my knowledge in that area has been mostly outdated. I have some ideas of a data centric web site with interactive data visualization and the question is what tool do I use to implement this idea? To educate myself, I […]

In a recent coding review a coworker pointed out in my code that modifying a STL list might invalidate the iterators pointing to the elements in the list. That’s a good observation. I know STL map will not invalidate iterators when elements are inserted or erased from the container. But for STL list, I can’t […]

Finally! After a few weeks of waiting in line then gave up to ordering online then gave up routine, I have gotten my own iPad 2! It’s a gift from my wife who understands my nerdiness, unlike this person’s wife. After playing with it for a few days I would like to share some unbiased opinions. I […]
